Abstract

A transport and storage container for liquids has an inner plastic container having an upper bottom with a fill socket, two sidewalls, a front wall with an outlet socket at the lower edge, a back wall, and a lower drainage bottom slanted toward the outlet socket. A pallet-shaped underframe has a support bottom for receiving the lower bottom of the inner container. The front wall of the inner container has a dome-shaped bulge where the outlet socket is arranged. Two bottom portions are arranged on opposed sides of the bulge and ascend from the lower bottom toward the front wall and the corner areas adjoining the front wall or toward the front wall and the sidewalls and the corner areas adjoining the front wall and the sidewalls. They form drainage surfaces for residual liquid to be drained from the forward bottom area into the outlet socket when removing residual liquid.
